Lululemon Athletica Open Back Top

Lululemon Athletica Open Back Top Heathered gray. High neck. Open back to show cute bralette if desired. Thumb holes. Back zip pocket. Moisture wicking fabric with anti odor technology. Tags have been removed but this appears to be a 6. I'm a 4 and it fits but is slightly loose (refer to pics). If you like a more fitted look it's a 6, for a looser fit it can fit a 4. EUC - like new - no rips, stains, pilling or flaws
